RESUMEN

OBJETIVO:

Mostrar dos casos de oclusión espontánea de remanente malformativo previamente embolizado y analizar sus probables causas.

MÉTODO:

Revisión retrospectiva de pacientes con malformaciones arteriovenosas cerebrales (MAV) embolizadas entre Enero de 1999 y Agosto de 2005 en nuestra institución y análisis de dos casos de oclusión de MAV remanentes.

RESULTADOS:

Se presentan dos casos de MAV tratadas por vía endovascular, con remanentes del nido malformativo post-embolización, que posteriormente en controles angiográficos presentan desaparición completa de las lesiones sin mediar otro tratamiento.

CONCLUSION:

La oclusión espontánea de un remanente arteriovenoso es un hecho infrecuente. Se discuten diversos mecanismos relacionados.
ABSTRACT

OBJECTIVE:

To report two cases of spontaneous occlusion of residual malformations that had previously been embolized and to analyze their probable causes.

METHOD:

Retrospective review of patients with embolized arteriovenous malformations (AVMs) between January 1999 and August 2005 in our institution and analysis of two cases of occlusion in residual AVMs.

RESULTS:

Two cases of AVMs that received endovascular treatment and had post-embolization residual nidus malformation, which in later angiographic controls showed a complete disappearance of the lesions without other treatment.

CONCLUSION:

The spontaneous occlusion of residual arteriovenous malformations is an infrequent occurrence. Several related mechanisms are discussed.
